Good night people,
I have a question regarding the optimization of the following loop:
for i=1:length(PV)
if i>3
if NL(i-1)<=100
if NL(i-2)<=100
if NL(i-3)<=100
u(i)=1;
else
u(i)=0;
end
end
end
end
end
I would like to reduce the if statements.
Thanks for your time,

t=double(NL(:).'<=100);
u=(movsum(t,[3,0])-t)>=3;

What should I do if I want to add more conditions, like in my example? And stored them in a u=zero(1,length(PV))
Thank you for your time

u=[0,0,0, conv(double(NL(:).'<=100),[1,1,1],'valid')>=3];
